Mold is one of those sneaky problems that can go unnoticed at first, but it can quickly become serious if left untreated.

Whether you’re tackling mold on drywall, behind the fridge, or along tile grout lines, these five steps will help you restore your home to a fresher, healthier state. Signs of Mold in the House Before you can clean mold, you need to identify where it’s hiding. Mold typically forms in warm, damp, and low-light environments. These conditions are common in bathrooms, kitchens, laundry areas, basements, and around poorly insulated windows. Here are some warning signs: Black, green, gray, or white patches on walls or ceilings Persistent musty smells, even after cleaning Peeling or bubbling paint or wallpaper Sudden allergy symptoms or breathing issues that ease when you leave the room Pro-tip Mold often hides in places you don’t see. Behind drywall, under flooring, or inside HVAC vents are common locations. If there’s a strong odor but no visible signs, a mold detection kit or a professional inspection may be necessary.

People with allergies, asthma, or compromised immune systems are especially sensitive. Common reactions to mold include: Nasal congestion and sneezing Chronic coughing or wheezing Eye irritation or skin rashes Fatigue and headaches In some cases, long-term exposure to mold spores can cause more severe respiratory problems.

Important Never mix vinegar with bleach or ammonia. This creates a chemical reaction that produces toxic fumes. Chemical Cleaners For larger infestations or tougher surfaces: EPA-registered mold removers Diluted bleach (1 cup bleach per gallon of water) for non-porous materials like tile and sealed concrete Isopropyl alcohol (70%) for electronics, tools, and smaller objects Dreame Take A Dreame wet-dry vacuum is ideal for this process.
